how many va/watts ups should I buy for my desktop and ps4?

[shadybk]

voltage and watts is something I don't understand, so I need help with how many watts the ups will need to support:
my gaming pc with a 650w power supply, but according to pc part picker it is only using 450 watts
my ps4: I think uses about 137 watts when on
my 42inch plasma tv, uses 103 watts
and my monitor uses 26 watts

thanks in advance

If you're in the US, don't worry about Voltage so stop reading this paragraph here. If you're outside of the US, you'll just have to make sure your computer's power supply is set to the correct voltage for your area. You'll also have to make sure you get a PSU that matches your computer, TV, and PS4's voltage setting (110V or 220V). In short, you'll need to make sure you're matching the Voltage for all items, including whatever Voltage is coming out of your wall outlets.

Wattage is basically a measure of how much power is being used by each item.

Are you wanting to run your TV, PS4, monitor, and computer if the power goes out? Keep in mind that a PSU will only last for about 15 minutes before running out of juice. It's just meant to let you get to a save point rather than keep you running through a power outage. You'd need a generator for that.

If you're going to buy now, I wouldn't skimp out. If you want to run them all, you'll want to get a UPS that can support all devices at full bore. Otherwise, you could run the risk of under powering one or all devices which can cause damage.

Unfortunately, you'd be right over the 900W line, which seems to be a common step in UPSs so you'll probably need a 1000W UPS. Not cheap.

You'll also need to make sure it has enough outlets for your devices. I assume they would need one each for a total of 4 outlets but that's won't be a problem, give the Wattage. I'd personally suggest plugging your modem and router into this device as well. A 1000W supply will cover those.

You could take a change and go down to assuming your PC only pulls 450W. That will greatly cut your costs.

You could also only plug in your PC and monitor and get a UPS that covers those. That will let you shut your computer down properly in the case of a power outage. That would be the most practical way to protect your system. The other devices won't have an issue.

Here's a link to NewEgg that will show PSUs that will cover the first scenario I talked about:

Also, to make things a little simpler for you, ignore VA. It's an alternative way to measure "power". It will be simpler for you to just pay attention to Wattage.

Do you normally have everything on at the same time while the PC is running stress tests to achieve maximum power draw? Even if you did a UPS like http://www.newegg.com/Product/Product.aspx?Item=N82E16842102048 should be good enough.

I did more research and found out that I need a ups with regular sine waves, not simulated because modern psu's won't work with simulated sine waves, but the regular sine wave ups are expensive, I'm starting to think I might not even get one at this point since they're doing to be so expensive

It's not always true, but you can buy a CyberPower CP1500PFCLCD: http://www.newegg.com/Product/Product.aspx?Item=N82E16842102134

I think I'll go with the 600w $140 version of the ups that you linked, you think 600w should be enough for my desktop which draws a maximum of 420 watts when in full load and a ps4 that uses a maximum of 140 watts? 600w should be just enough to give me a few minuted to power down safely right?

If only the PC and the monitor are powered on and used, then it's enough. Same for the ps4 and the TV even when the PC and monitor are powered on as long as the PC is idle or at least not working too hard (exceeding the UPS rating will cause it to shutdown). You have enough info to determine if the 600W is enough, but if I were you I'd seriously consider the 810W (1350VA) version simply because batteries wear out and the UPS can't maintain power for as long as it does when batteries are brand new. I also prefer not to load a UPS above 70% of its rating for that reason.

do you know how expensive the batteries are for the 600w model and how long a battery lasts on average?
this doesnt say how many watts it is just that it is a replacement?

Batteries usually last 3-5 years, but it depends on how often the UPS has to switch to batteries. You can buy the original battery, but a battery like http://www.amazon.com/CyberPower-CP1000PFCLCD-12V-9Ah-Battery/dp/B00G5EJ5PQ/ref=sr_1_2?ie=UTF8&qid=1451503975&sr=8-2&keywords=CyberPower+CP1000PFCLCD+Replacement+Battery is as good. You can also buy them locally at most battery store because there is nothing special to an inexpensive UPS battery (it also is a 9Ah battery). Batteries are rated in Ah (Amperes per hour), not in watts.

thank you, so if all of the ups systems with different voltage and watts use the same battery, why are they limited in how much wattage they supply?

More powerful UPS like the 1500VA use 2 batteries. Other than batteries, internal components determine their rating. My APC Smart UPS use 2 batteries, but they are not the same. With 2 batteries, the Cyberpower 1350VA can provide backup for longer than the 1000VA, but it costs $40 more and you need to replace 2 batteries instead of only one..
